Inboxen is a service that provides you with an infinite number of unique inboxes. It's not designed to replace your personal email address, but rather complement it. Every time a website asks for your email, click the "Add Inbox" button to create another email address. This leaves your personal address free from promotional offers and other junk mail.

This list was originally a clone of stackoverflow - List of Freely Available Programming Books by George Stocker.

The list was moved to GitHub by Victor Felder for collaborative updating and maintenance. It grew to become one of the most popular repositories on Github, with over 80,000 stars, over 4000 commits, over 800 contributors, and over 20,000 forks.

The repo is now administered by the Free Ebook Foundation, a not-for-profit organization devoted to promoting the creation, distribution, archiving and sustainability of free ebooks. Donations to the Free Ebook Foundation are tax-deductible in the US.

This site shows pictures and objects around the CURTA computing machine - in the sense of appreciation of this extraordinary mechanical marvel. The objects come from different sources and were published with the permission of their owners - and therefore this is not an integrated Curta collection.
